"""Test the wallet backup features.
|
|
|
|
Test case is:
|
|
4 nodes. 1 2 and 3 send transactions between each other,
|
|
fourth node is a miner.
|
|
1 2 3 each mine a block to start, then
|
|
Miner creates 100 blocks so 1 2 3 each have 500 mature
|
|
coins to spend.
|
|
Then 5 iterations of 1/2/3 sending coins amongst
|
|
themselves to get transactions in the wallets,
|
|
and the miner mining one block.
|
|
|
|
Wallets are backed up using dumpwallet/backupwallet.
|
|
Then 5 more iterations of transactions and mining a block.
|
|
|
|
Miner then generates 101 more blocks, so any
|
|
transaction fees paid mature.
|
|
|
|
Sanity check:
|
|
Sum(1,2,3,4 balances) == 114*500
|
|
|
|
1/2/3 are shutdown, and their wallets erased.
|
|
Then restore using wallet.dat backup. And
|
|
confirm 1/2/3/4 balances are same as before.
|
|
|
|
Shutdown again, restore using importwallet,
|
|
and confirm again balances are correct.
